The Supernova M99 Pro Dynamo Front Light is a revolutionary product. It's the world's first dynamo - operated LED front light with high beam function and German road code approval. Boasting a matrix of 11 LEDs and advanced control electronics, it can produce light values up to 1,000 lumens and 200 lux, a feat previously only achieved by high - performance e - bike front lights. This gives classic mountain bikes a stronger environmental edge and equal safety on the roads. Once installed, it's completely maintenance - free. It'll illuminate your path for years, with its light intensity automatically adjusting to your speed. As soon as you enter a tunnel, in a split second, it switches to a bright dipped beam with a luminous flux up to 600 lumens.

Using the Supernova M99 Pro Dynamo Front Light is easy. Just install it on your bike following the included instructions. As you pedal, it will start generating power and lighting up. The light intensity will change based on your speed. When you enter a tunnel or a dark area, it will automatically switch to a bright dipped beam. For maintenance, since it's maintenance - free, you don't need to do much. But it's a good idea to keep it clean and check the connections occasionally. Avoid exposing it to extreme temperatures or water for long periods. If you notice any issues with the light, such as dimming or not turning on, check the dynamo and the connections first.
